Expression of the cutaneous lymphocyte antigen and the alpha IEL beta 7 integrin by intraepithelial lymphocytes in healthy and diseased human gingiva.

Abstract excerpt

The presence of specific phenotypes of intraepithelial lymphocytes (IEL) was determined in healthy and diseased gingiva by immunohistochemistry. The cutaneous lymphocyte antigen (CLA) and the alpha IEL beta 7 integrin were detected with the HECA-452 and with the HML-1 monoclonal antibodies, respectively. Some 24-62% of CD3-positive intraepithelial lymphocytes expressed the CLA antigen in the junctional...
